Median Sale Price The median sale price p (in thousands of dollars) of an existing one-family home in the United States from 2002 through 2014 (see figure) can be approximated by the model p ( t ) = { − 0.757 t 2 + 20.80 t + 127.2 , 2 ≤ t ≤ 6 3.879 t 2 − 82.50 t + 605.8 , 7 ≤ t ≤ 11 − 4.171 t 2 + 124.34 t − 714.2 , 12 ≤ t ≤ 14 where t represents the year, with t = 2 corresponding to 2002. Use this model to find the median sale price of an existing one-family home in each year from 2002 through 2014. ( Source: National Association of Realtors )

Solution Summary: The author explains the function f, which is a well-defined relation between two variables so that for each and every value of independent and dependent variables, there exists only one value.
